Sapphire material has extremely high transmittance in the visible and near-infrared light bands, usually not less than 84.5%.This enables the specific wavelength light required for hair removal generated by the light source to be efficiently transmitted in the sapphire light guide block, minimizing the loss of light energy and ensuring sufficient energy reaches the skin hair follicles.

Firstly, the hardness of high hardness sapphire material is second only to diamond, with a Mohs hardness of 9.Although the frequent use of hair removal devices requires contact with various objects such as cleaning tools, oil and dust on the skin surface, etcThe high hardness sapphire light guide block can prevent scratches and wear, and can maintain the smoothness and optical performance of the product surface for a long time. It is precisely these characteristics that make the light guide block product of the hair removal device have a long service life.In contrast, some light guiding materials with lower hardness are prone to scratches on their surfaces after a period of use, which can affect the transmission of light energy.

Secondly, when the hair removal device is working, the light source will generate a large amount of heat, and the light guide block in the hair removal device will absorb some of the heatSapphire has excellent thermal stability, with a melting point of up to 2045 ℃, allowing the light guide block to operate continuously and stably at higher temperatures without deformation or performance degradation.

Sapphire has good chemical stability and hardly reacts with common chemicals such as acids and bases.In the usage environment of hair removal devices, there may be contact with sweat secreted by the skin, residual skincare products, and cleaning agents used during the cleaning process.Sapphire light guide blocks can resist the erosion of these chemicals and maintain the stability of their physical and optical properties.
